Email Average Order Value

Definition

Average order value from email, or email AOV, measures the mean transaction amount of purchases attributed to email marketing campaigns. It is calculated by dividing total email-attributed revenue by the number of email-attributed orders over a given period. Email AOV varies significantly by campaign type, product category, and subscriber segment. Industry benchmarks indicate that email AOV typically runs 10% to 20% higher than AOV from other channels such as social media, paid search, or display advertising, largely because email audiences are more familiar with the brand and further along in the buying cycle when they click through.

Email AOV is not a fixed metric — it fluctuates based on what you send and to whom. Abandoned cart emails, for example, tend to have AOVs equal to or slightly above the site average because the subscriber was already buying. Promotional campaigns featuring discounts or clearance items often show lower AOVs because they attract price-sensitive buyers. Welcome series emails, by contrast, frequently produce the highest AOV of any campaign type — sometimes 25% to 40% above site average — because new subscribers are given a curated selection of best-selling products or a first-purchase offer that encourages basket building.

Best Practices

• Segment your AOV analysis by campaign type and subscriber cohort, not just overall: Reporting a single AOV number hides the fact that welcome series and product recommendation emails may deliver 50% higher AOV than promotional blasts. Use campaign-type breakdowns to identify which email strategies drive basket size and double down on them. Segment further by new vs returning customers, as return customers typically produce 20% to 30% higher order values.

• Use cross-sell and upsell recommendations directly inside emails: Embedding personalised product recommendations based on browsing or purchase history can lift AOV by 10% to 30%. The key is to recommend complementary items — a case for a phone, a charger for a laptop — rather than random bestsellers. Dynamic content blocks that update based on the individual subscriber's data are essential for this approach.

• Set free shipping thresholds that nudge subscribers toward higher basket values: If your average email AOV is £50 and you set free shipping at £60, a meaningful percentage of subscribers will add items to reach the threshold. Analyse the distribution of order values to find the threshold that maximises incremental revenue without giving away shipping profit on orders that would have been larger anyway.

• Use bundle offers and multi-buy pricing in email campaigns: Bundles naturally increase AOV because they package multiple items at a perceived discount. Email is an ideal channel for promoting bundles because you can target subscribers who have shown interest in one of the bundled products. Multi-buy offers such as "buy two, get 20% off the third" push subscribers to add more items than they originally intended.

• Compare email AOV against channel-specific costs when evaluating performance: Email might have a slightly lower AOV than paid search for some product categories, but email's cost per acquisition is typically 80% to 90% lower. AOV should always be evaluated in context of customer acquisition cost, not in isolation. A channel with high AOV and high CAC may be less profitable than a channel with moderate AOV and near-zero marginal cost.
